RESUMO

CONTEXT: The Centers for Disease Control and Prevention (CDC) developed a workforce training on sexual and gender minorities (SGMs). OBJECTIVE: This article describes the evaluation of the training. DESIGN: Participants completed pre- and posttest surveys. After the pilot evaluation, some improvements were made to the curriculum and to the pre- and posttest questionnaires. Participants in subsequent (implementation) training were similarly asked to complete pre- and posttest questionnaires. SETTING: CDC. PARTICIPANTS: CDC staff. MAIN OUTCOME MEASURES: Participants' knowledge, ally identity, and perceptions of SGMs. RESULTS: Pilot and implementation training data showed increases in participant knowledge of 44% and 49%, respectively, increases in ally identity of 11% and 14%, respectively, and increases in positive perceptions of SGM of 25% and 31%, respectively. CONCLUSION: These results suggest that the CDC Ally Training may be a useful tool for improving staff knowledge and perceptions of SGM people.

RESUMO

Introduction: The COVID-19 pandemic forced rapid adoption of telemedicine for care of neurology patients. This study contributes to this literature by describing the structure and implementation of telemedicine-based outpatient neurology clinics at the UCLA Medical Center and estimates patient cost savings, before and after the California COVID-19 "Safer at Home" directive, and patient satisfaction. Methods: This was a retrospective, nonrandomized, case series study of telemedicine-based neurological management in an urban academic medical center from October 2018 to June 2020. We estimated roundtrip travel time, roundtrip travel distance, total savings, and surveyed patient and provider satisfaction with telemedicine care. We supported these findings through evaluation of 7,194 patients by telemedicine and conducted 9,189 video visits for neurological care. Results: The median telemedicine patient avoided a roundtrip driving distance of 33 miles and roundtrip travel time of 75 min. Within sample, median hourly earnings were $27/h. The median patient saved $18 on fuel and parking and $36 of time-based opportunity savings, for total savings of $54 per video visit. Eighty-six percent of patients surveyed were satisfied with their video visit experience. Conclusions: Telemedicine reduced travel time and also reduced costs for neurology patients. Patients and providers both reported high levels of satisfaction with telemedicine.

RESUMO

CONTEXT: There is limited research on what factors are most salient to implementation of evidence-based practices (EBPs) among public health agencies in public health emergency preparedness and response (PHPR) and under what conditions EBP implementation will occur. OBJECTIVE: This study assessed the conditions, barriers, and enablers affecting EBP implementation among the PHPR practice community and identified opportunities to support EBP implementation. DESIGN: A Web-based survey gathered information from public health agencies. Data obtained from 228 participating agencies were analyzed. SETTING: State, local, and territorial public health agencies across the United States. PARTICIPANTS: Preparedness program officials from 228 public health agencies in the United States, including Public Health Emergency Preparedness (PHEP) cooperative agreement awardees (PHEP awardees) and a random sample of local health departments (LHDs). RESULTS: Respondents indicated that EBP is necessary and improves PHPR functions and tasks and that staff are interested in improving skills for EBP implementation. Top system-level barriers to EBP implementation were insufficient funding, lack of EBP, and lack of clarity regarding which practices are evidence based. PHEP awardees were significantly more likely to report a lack of EBP in the field, whereas LHDs were significantly more likely to report a lack of incentives. The top organizational-level barrier was insufficient staff. Most respondents indicated their agency culture supports EBP; however, LHDs were significantly more likely to report a lack of support from supervisors and leadership. Few respondents reported individual barriers to EBP implementation. CONCLUSIONS: Findings indicate an opportunity to improve dissemination strategies, communication efforts, and incentives to support EBP implementation in PHPR. Potential strategies include improving awareness of and accessibility to EBPs through targeted dissemination efforts; building organizational capacity to support EBP implementation, particularly staff capacity, knowledge, and skills; and identifying funding and incentives to promote EBP uptake and sustainment.

RESUMO

In the 21st century, the ancient mind-body practice of yoga has surged in popularity among western enthusiasts for its numerous health benefits. Particularly, a growing evidence base supports yoga for cultivating positive embodiment and reducing risk for disordered eating. Nevertheless, amidst its rise are concerns about yoga's departure from its spiritual foundations and increasing assimilation into the appearance- and commercial-driven exercise and fitness culture. Consequently, an exclusionary identity has been perpetuated in shaping norms surrounding who can and does practice yoga, which contradicts earlier egalitarian visions of a yoga for all. Therefore, we adopt a social justice lens in offering a focused analysis of the intersection of yoga, embodiment, and inclusion for select marginalized social identities typically underrepresented among yoga practitioners and in yoga scholarship. Data are synthesized from both qualitative and quantitative sources and integrate an understanding of how confined media representations of "the yoga body" and other practical constraints may undermine the perceived access to the practice for members of diverse groups. We conclude with inviting future considerations towards fostering more interdisciplinary community-based research partnerships among the variety of stakeholders invested in advancing the accessibility and inclusion of yoga and positive embodiment for all bodies.

RESUMO

BACKGROUND: Disaster citizen science, or the use of scientific principles and methods by "non-professional" scientists or volunteers, may be a promising way to enhance public health emergency preparedness (PHEP) and build community resilience. However, little research has focused on understanding this emerging field and its implications for PHEP. To address research gaps, this paper: (1) assesses the state of disaster citizen science by developing an inventory of disaster citizen science projects; (2) identifies different models of disaster citizen science; and (3) assesses their relevance for PHEP. METHODS: We searched the English-language peer-reviewed and grey literature for disaster citizen science projects with no time period specified. Following searches, a team of three reviewers applied inclusion/exclusion criteria that defined eligible disasters and citizen science activities. Reviewers extracted the following elements from each project: project name and description; lead and partner entities; geographic setting; start and end dates; type of disaster; disaster phase; citizen science model; and technologies used. RESULTS: A final set of 209 projects, covering the time period 1953-2017, were included in the inventory. Projects were classified across five citizen science models: distributed or volunteer sensing (n = 19; 9%); contributory (n = 98; 47%); distributed intelligence (n = 52; 25%); collaborative research (n = 32; 15%); and collegial research (n = 8; 4%). Overall, projects were conducted across all disaster phases and most frequently for earthquakes, floods, and hurricanes. Although activities occurred globally, 40% of projects were set in the U.S. Academic, government, technology, and advocacy organizations were the most prevalent lead entities. Although a range of technologies were used, 77% of projects (n = 161) required an internet-connected device. These characteristics varied across citizen science models revealing important implications for applications of disaster citizen science, enhancement of disaster response capabilities, and sustainability of activities over time. CONCLUSIONS: By increasing engagement in research, disaster citizen science may empower communities to take collective action, improve system response capabilities, and generate relevant data to mitigate adverse health impacts. The project inventory established a baseline for future research to capitalize on opportunities, address limitations, and help disaster citizen science achieve its potential.

RESUMO

Objectives As the U.S. healthcare system shifts toward collaboration, demand for leaders with interdisciplinary skills increases. Leadership competencies guide interdisciplinary training programs; however, identifying cost-effective methods for evaluating leadership competencies is challenging, particularly when interdisciplinary trainees have different areas of expertise and professional goals. Traditional pre-/post-testing, a common method for evaluating leadership competencies, is subject to response-shift bias, which can occur when participants' understanding of a construct changes between pre- and post-test. As a result, participants may rate their knowledge of the construct lower at post-test. Retrospective pre-tests are one method thought to reduce response-shift bias in pre-/post-tests. The current study explores the use of a retrospective pre-test to control for response-shift bias in an interdisciplinary training program. Methods Over three cohort years, thirty-four trainees from an interdisciplinary leadership program completed a self-assessment aligned with MCH leadership competencies. The traditional pre-test self-assessment was completed at the beginning of the training program. The retrospective pre-/post-test self-assessment was completed at the end of the training program. Results Retrospective pre/post-test scores indicate significant self-reported increases in all 24 leadership areas (p ≤ .001). Furthermore, participants' self-ratings were significantly higher on the traditional pre-test for all 24 areas than on the retrospective pre-test (p ≤ .001). Conclusions for Practice Retrospective pre-tests appeared to control for response-shift bias and may be a cost-effective way to evaluate trainee change within an interdisciplinary leadership program. These findings suggest the methodology's usefulness in interdisciplinary training and its potential use in the broader world of community-based MCH training initiatives.

RESUMO

We discuss challenges to implementing evidence-based practice within the broad field of public health preparedness and response. We discuss the progress of public health preparedness and response in building and translating evidence to practice since the World Trade Center attacks of 9/11/2001. We briefly describe analogies to struggles that other professional disciplines face, and we highlight key factors that facilitate and impede the implementation of evidence-based practice. We recommend a partnership led by funding agencies and closely involving research organizations and professional associations as a means to ensure that the public health preparedness and response field continues to develop an evidence-based culture and practice.

RESUMO

Through semi-structured interviews with 36 International Board Certified Lactation Consultants (IBCLCs) who assist mothers with breastfeeding, this study takes a systematic look at breastfeeding disparities. Specifically, this study documents race-based discrimination against patients in the course of lactation care and links the implicit bias literature to breastfeeding disparities. IBCLCs report instances of race-based discrimination against patients such as unequal care provided to patients of color and overt racist remarks said in front of or behind patient's backs. This study connects patient discrimination in lactation to institutional inequality and offers suggestions to address these inequities.

RESUMO

CONTEXT: The experiences of communities that responded to confirmed cases of Ebola virus disease in the United States provide a rare opportunity for collective learning to improve resilience to future high-consequence infectious disease events. DESIGN: Key informant interviews (n = 73) were conducted between February and November 2016 with individuals who participated in Ebola virus disease planning or response in Atlanta, Georgia; Dallas, Texas; New York, New York; or Omaha, Nebraska; or had direct knowledge of response activities. Participants represented health care; local, state, and federal public health; law; local and state emergency management; academia; local and national media; individuals affected by the response; and local and state governments. Two focus groups were then conducted in New York and Dallas, and study results were vetted with an expert advisory group. RESULTS: Participants focused on a number of important areas to improve public health resilience to high-consequence infectious disease events, including governance and leadership, communication and public trust, quarantine and the law, monitoring programs, environmental decontamination, and waste management. CONCLUSIONS: Findings provided the basis for an evidence-informed checklist outlining specific actions for public health authorities to take to strengthen public health resilience to future high-consequence infectious disease events.

RESUMO

Background: Botulism manifests with cranial nerve palsies and flaccid paralysis in children and adults. Botulism must be rapidly identified and treated; however, clinical presentation and treatment outcomes of noninfant botulism in children are not well described. Methods: We searched 12 databases for peer-reviewed and non-peer-reviewed reports with primary data on botulism in children (persons <18 years of age) or botulinum antitoxin administration to children. Reports underwent title and abstract screening and full text review. For each case, patient demographic, clinical, and outcome data were abstracted. Results: Of 7065 reports identified, 184 met inclusion criteria and described 360 pediatric botulism cases (79% confirmed, 21% probable) that occurred during 1929-2015 in 34 countries. Fifty-three percent were male; age ranged from 4 months to 17 years (median, 10 years). The most commonly reported signs and symptoms were dysphagia (53%), dysarthria (39%), and generalized weakness (37%). Inpatient length of stay ranged from 1 to 425 days (median, 24 days); 14% of cases required intensive care unit admission; 25% reported mechanical ventilation. Eighty-three (23%) children died. Median interval from illness onset to death was 1 day (range, 0-260 days). Among patients who received antitoxin (n = 193), 23 (12%) reported an adverse event, including rash, fever, serum sickness, and anaphylaxis. Relative risk of death among patients treated with antitoxin compared with patients not treated with antitoxin was 0.24 (95% confidence interval, .14-.40; P < .0001). Conclusions: Dysphagia and dysarthria were the most commonly reported cranial nerve symptoms in children with botulism; generalized weakness was described more than paralysis. Children who received antitoxin had better survival; serious adverse events were rare. Most deaths occurred early in the clinical course; therefore, botulism in children should be identified and treated rapidly.

RESUMO

Due to the fast pace and high complexity of managing patients in intensive and acute care units (ICUs), healthcare students often feel challenged and unprepared to practice in this environment. Simulations and standardised patients provide "hands-on" learning experiences that are realistic and help students to gain competence and confidence. This study examined the impact of an intensive case simulation laboratory using a patient simulator and standardised patients on students' perceptions of their confidence and preparedness to work in acute care settings. Second-year Masters of Occupational Therapy (MOT; n = 127) and Doctor of Physical Therapy (DPT; n = 105) students participated in a three-hour intensive care simulation laboratory comprised of four stations that were designed to simulate common ICU patient care scenarios. Data analysed were student pre- and post-simulation surveys and written comments, and clinical instructors' (CIs; n = 51) ratings on DPT students' preparedness and confidence within the first two weeks of their acute care internships obtained after the laboratory. There was a significant increase for DPT (p < 0.0001) and MOT (p < 0.10) students in median ratings of how prepared they felt to practice in acute care settings following the ICU simulation compared to before the laboratory. CIs rated the DPT students as either prepared or very prepared for and moderately confident or very confident in the acute care setting. The use of simulation training using standardised patients and patient simulators was beneficial in increasing student confidence and preparing OT and PT students to practice in the acute care setting. Health professional educators should consider using an interprofessional simulation experience to improve their students' confidence and preparedness to provide appropriate care in the acute setting.

RESUMO

The white male norm hypothesis (Zárate & Smith, 1990) posits that White men's race and gender go overlooked as a result of their prototypical social statuses. In contrast, the intersectional invisibility hypothesis (Purdie-Vaughns & Eibach, 2008) posits that people with membership in multiple subordinate social groups experience social invisibility as a result of their non-prototypical social statuses. The present research reconciles these contradictory theories and provides empirical support for the core assumption of the intersectional invisibility hypothesis-that intersectional targets are non-prototypical within their race and gender ingroups. In a speeded categorization task, participants were slower to associate Black women versus Black men with the category "Black" and slower to associate Black women versus White women with the category "woman." We discuss the implications of this work for social categorical theory development and future intersectionality research.

RESUMO

In the United States, selected subgroups of historically marginalized populations include people with disabilities and people in racial/ethnic minority groups ("critical populations") who have been disproportionately affected by COVID-19. These groups are also more likely to use public transit to access essential resources; thus, understanding transit agencies' communication strategies to reach these populations during crises is of utmost importance. We conducted a content analysis of 16 transit agencies' webpages and Twitter® accounts during the first 6 months of the pandemic to assess alignment of agencies' COVID-19-related communications with best practices in crisis communication across five themes: perceivability, navigability, understandability, suitability, and content. Findings suggested that transit agencies frequently communicated about schedule changes and safety, eg, masking, station sanitation, and reflected racial/ethnic diversity in images. Yet, less than half consistently used communication strategies known to enhance accessibility and uptake of messaging among critical populations, eg, alternative text, and even less reflected disability diversity in images. We offer recommendations for public transit agencies to move beyond compliance to effectively address the needs of ridership most substantially impacted by public health emergencies.

RESUMO

The COVID-19 pandemic revolutionized cancer care delivery leading to rapid adoption of digital technology for telehealth in the United States. In this study, we describe telehealth utilization trends across the three largest waves of the pandemic at a safety net academic center. We also provide a perspective on lessons learnt and our vision for cancer care delivery using digital technology in the near future. The integration of interpreter services within the video platform and its integration within the electronic medical record system is crucial for safety net institutes that service a diverse patient population. Pay-parity for telehealth, especially ongoing support for audio-only visits, will be critical in overcoming health disparities for patients without access to smartphone technology. Use of telehealth in clinical trials, widespread adoption of hospital at home programs, electronic consults for rapid access, and structured telehealth slots in clinic templates will be crucial in making cancer care more equitable and efficient.

RESUMO

Multiple cases of nail salon workers with occupational exposure to acetone, toluene, and acrylic monomers, namely methyl methacrylate and cyanoacrylates, presented separately to our clinic with similar complaints of factitious gingival stomatitis and formication--an abnormal sensation like ants crawling on or inside the skin. Recognizing oral manifestations resulting from possible toxic chemical exposure is not generally thought to be within the realm of most dental practices, yet to assure appropriate care, dentists must be vigilant and include thorough patient interviews in the diagnostic equation.

RESUMO

OBJECTIVE: Although many autistic adults show high posttraumatic stress, PTSD is underdiagnosed in this population. This study aims to examine correlates of autistic adults screening positive for PTSD (PTSD +) and predictors of a professional PTSD diagnosis (Diagnosis +) in the PTSD + subgroup. METHOD: Self-identified autistic adults (N = 677) completed an online survey on their demographic characteristics, mental health symptoms, and trauma history. T tests and chi-squares were used to compare subgroups, and logistic regression was used to predict diagnosis status. RESULTS: PTSD + participants were less likely to be employed or to identify as cisgender men, had more mental health symptoms and worse functional impairment, and had experienced a higher number of traumas and more interpersonal trauma. The same was true for Diagnosis + participants, who were also older and more likely to have a marginalized racial/ethnic identity. Among participants who were PTSD +, older age, being a woman or gender minority, being unemployed or on disability, having increased posttraumatic stress, having more co-occurring conditions, and having lower functional impairment predicted being Diagnosis +. The final model explained 35% of variance in diagnosis. CONCLUSION: PTSD is associated with significant impairment in autistic adults, but it often goes unrecognized. In particular, autistic cisgender men might be underdiagnosed with PTSD because of gendered stereotypes. High functional impairment may also increase barriers to obtaining an appropriate diagnosis. Future research should include participant treatment history as a potential factor. Clinicians should be aware of these potential signs of PTSD and diagnostic barriers when working with autistic clients. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMO

Groundwater biota are crucial for the ecological functioning of subterranean ecosystems. However, while knowledge of the taxonomic diversity of groundwater invertebrates (stygofauna) is increasing, functional ecological information is still limited. Here, we investigate seldom empirically tested assumptions around stygofaunal trophic plasticity in coping with oligotrophic habitats. We focus on Barrow Island (Western Australia), an ideal natural laboratory due to the occurrence of natural oil seeps in association with aquifers. The trophic position and food source use of the endemic atyid shrimp Stygiocaris stylifera (Holthuis, 1960) were assessed via δ13C and δ15N stable isotope analysis (SIA). Background information on the environmental conditions was gathered through hydrochemical data and δ13C SIA combined with 14C data from dissolved inorganic/organic carbon and particulate organic carbon from groundwater samples. Our results indicate carbon enrichment in proximity to the natural oil seepage coupled with changes in trophic positions of S. stylifera from higher consumers/predators to biofilm grazers/decomposers. These results are consistent with an increased involvement of hydrocarbon seeps and associated microbial communities in the carbon flows and confirm potential for the trophic flexibility in stygofauna. Further investigations involving other trophic groups will help elucidate the functioning of the ecosystems at a community level.

RESUMO

The present pilot randomized controlled trial (RCT) evaluated the feasibility, acceptability, and preliminary efficacy of a 4-week online yoga and body gratitude journaling intervention for strengthening positive embodiment among racially-diverse higher weight college women. Seventy-five participants were initially randomized to either the yoga condition (n = 36) or to a wait-list control (n = 39). Participants completed measures of positive and negative body image, weight bias internalization, self-compassion, drive for leanness, and physical activity acceptance at both baseline and post. Preliminary results among the 42 analyzed completers (mean age = 20.9, SD = 2.4; 30% Black or African American) revealed acceptable feasibility given the low-intensity nature of the intervention reflected in a 36% attrition rate. Self-reported adherence was strong for the yoga component with 81% of participants indicating that they practiced with the videos ≥3-4 times per week as suggested. Although 71% reported completing the body gratitude journal ≥1-2 times per week, daily adherence was minimal. Acceptability was also high among participants randomized to the yoga condition as indicated by 86% expressing at least moderate levels of satisfaction with the overall program. Qualitative feedback from participants further supported the acceptability of the program and pointed to important areas in further refining the protocol in the future. Preliminary efficacy was supported by significant reductions in internal body shame and gains in body appreciation, functional body appreciation, functional body satisfaction, functional body awareness, and behavioral commitment to physical activity engagement among the yoga vs. wait-list control participants. These promising findings once replicated in larger, higher-powered trials may have important implications for extending the reach and accessibility of mind-body wellness practices like yoga to benefit racially-/ethnically-diverse college women of higher weight. This research is further responsive to the growing need for efficacious remotely-delivered, and scalable behavioral health interventions in the ongoing era of the COVID-19 pandemic. However, additional research is warranted to explore ways of enhancing engagement of participants with lower levels of positive embodiment and to further incentivize the journaling component of the intervention.
